What Is Oxidation?

Oxidation occurs when the gel coat or paint on your boat reacts with oxygen, salt, and UV rays. This chemical reaction breaks down the surface, leaving a dull, chalky finish. If left untreated, oxidation penetrates deeper — making polishing harder later on.

  • → Light oxidation: Slight fading, water no longer beads off.
  • → Moderate oxidation: Noticeable haze, color dullness, rough texture.
  • → Heavy oxidation: Chalky white surface, deep color loss, heavy pitting.

How to Test for Oxidation

Rub a clean microfiber towel over the hull. If you see white residue, that’s oxidized gel coat. The more residue you see, the deeper the oxidation layer — and the more correction you’ll need.

Step-by-Step: Removing Oxidation from a Boat Hull

Follow these professional steps to safely bring your hull back to life.

  1. Wash Thoroughly
    Start with The Super Soaper to remove salt, grime, and oxidation dust. Rinse and dry completely with a Massive Drying Towel.
  2. Polish Away Oxidation
    Use Picture Perfect Polish — a one-step compound and polish that cuts oxidation fast while finishing to a glossy shine.
  3. Choose the Right Pad
    For heavy oxidation, use a wool pad. For moderate or finishing stages, switch to foam. Work small sections slowly with overlapping passes.
  4. Inspect Your Work
    After polishing, wipe down and check your reflection. Repeat if necessary for stubborn spots or deeper fading.
  5. Seal with Ceramic Protection
    Lock in your restored shine using Tough As Shell Ceramic Spray. It provides UV, salt, and oxidation resistance for months.
